APPARATUS FOR DIVIDING MEDICINAL OR OTHER POWDERS.

SPECIFICATION forming part of Letters Patent No. 370,351, datedSeptember 20, 1887.

Application filed April 26, 1887. Serial No. 236,138.

To all whom it may concern.-

Be it known that I, IRA ROBBINS, a citizen of the United States,residing at Camden, in the county of Camden, State of New Jersey,

have invented a new and useful Improvement in Apparatus for DividingMedicinal and other Powders, which improvement is fully set forth in thefollowing specification and accompanying drawings. w

to Myinvention relates to an apparatus for dividing powders; and itconsists of a cup rendered adjustable as to the size of the doserequired.

It further consists of means for supporting 1 5 said cup.

It further consists of means for preventing the cup from improperlyleaving its support.

It also consists of means for properly filling the cup.

It also consists of means for conveniently removing the cup from itssupport.

Figure 1 represents a vertical section of an apparatus embodying myinvention. Fig. 2 represents a top view of a portion thereof. Fig. 3represents a vertical section of another portion of the invention.

Similar letters of reference indicate corresponding parts in the severalfigures.

Referring to the drawings, A represents a standard which is secured toand rises from a base, B, the latter having a drawer, O, forconveniently holding loose parts of the apparatus or other purposes. Thestandard is screwthreaded, as at a, and formed with a shoulder, 3 5 b,above which latter the standard has a plain surface.

D represents a flanged head having a central opening, so as to befittedon the standard and rested on the shoulder b thereof. In the head,near the periphery thereof, are openings 0, in the present case twelvein number, the same extending vertically and receiving cups E, whichhave their upper ends fianged,where-.

by they may besuspended from the head within said openings 0. The baseof each cup E is perforated, and through the same is passed the stem Fof a piston, G, it being evident that the piston may rise and fall inthe cup.

On the standard, above thehead D, is placed an annular plate, H, whichis made of metal (No model.)

or other material, so as to be sufficientl y heavy, and of such diameteror size that its periphery rests on the inner edges of the upperends ofthe cups E, whereby the latter are prevented from improperly rising fromthe head D.

On the standard, above the plate H, is fitted a sleeve, J, having anarm, K, to which is secured abrush, L, the head of which is locatedbetween the periphery of the plate H and the rim or flange D of the headD.

M represents a follower which has a threaded opening in its center andis fitted to the threaded portion a of the standard A, it being locatedbelow the head D and adapted to support the pistons G, whose stems Frest on said follower.

Referring to Fig. 3, N representsabase having a stem, P, secured to andrising therefrom, and a series of openings, d, which latter are adaptedto register with the openings 0 of the 7c head D, and of such diameteras to receive the stems F of the pistons without permitting the cups Eto enter the same. A pin, Q, is secured to the base N in the openingtherein, so as to pass through an opening, 6, in the head D, for causingthe openings 0 d to register.

The operation is as follows: The sleeve J, with the brush L, andweight-plate H are removed, and the follower M is now or subse- 8oquently raised or lowered, so as to vertically adjust the pistons G, andthus regulate the depth of the cups Erelatively to the required size,dose, or charge of the powders, said cups E being in the openings 0 andthe stems F of 8 the pistons resting on the follower M, as will be seenin Fig. 1. The plate H and sleeve J, with the brush L, are now reappliedand a quantity of powder is placed on the head D, the flange or rim Dthereof forming a chamher to receive the powder. The brush L is nowrotated with.the sleeve J, whereby the powder is swept into the cups,and the latter are thus properly filled and contain uniform doses orcharges. In some cases a predeter- 5 mined quantity of powder is placedin the chamber or trough of the headD and the same brushed into thecups, so as to divide the powder into given quantities. Should the depthof the cups be insufficient to receive all of the powder, the followeris lowered, so as to increase said depth,'th us accommodating the cupsto the full amount of powder to be di-' vlded. Should it be desired tomake a dozen powders, every opening a is occupied bya cup E; Where aless number is required, blanks G are employed, the same being solid orclosed and occupylng the openings a similarly to the cups E, but areincapable of receiving powder. The brush L and plate H are now removed,and the head is also displaced from the standard A and then fitted onthe standard P. The stems F of the pistons G'drop into the openngs d ofthe base N but the cups Estrike the base and are thus raised, so thatthey may be grasped at the top and conveniently removed required.

from the head, after which they are overturned and the dose thusdischarged, the powders then belng put up in papers or otherwise, as

The head may afterward be restored to the standard A and the otheroperations repeated as desired.

The brush L is vertically adjustable on the arm K for evident purposes.

Having thus described my invention, what I clalm as new, and desire tosecureby Letters Patent, is-

1. An apparatus for dividing medicinal and other powders, consisting ofa base with standard, the latter having a shoulder, a head resting onsaid shoulder and having openings therein, cups resting in the openingsin said 7 head, and a second base with standard, said parts belugcombined as described.

2. In an apparatus for the purpose named, the combination of a base witha standard having a screw-threaded part and a shoulder with a headhaving openings therein, cups adapted to rest in said openings in thehead and having openings in their base, pistons within said cups, andshafts passing through the openings in the base of the said cups, a

follower working on said screw-threaded portion of standard andsustaining said pistonshafts, substantially as described.

3. An apparatus for dividing medicines, having a head loosely mounted ona standard and with openings therein, cups resting in said openings, anda brush secured to said standard and adapted to be brought in contactwith the mouth of said openings, substantially as and for the purposeset forth.

4. Ahead carrying-a cup, a standard supporting said head, and aweight-plate fitted to said standard,restiug on said cup, the partsbeing combined and operating substantially as described.

5. The combination, with the head D, having openings 0, of the cups Eand blanks G, substantially as and for the purpose set forth.

6. In an apparatus for the purpose named, the base N, having openings d,and standard P, in combination with head D, having openings o, and thecups E, resting in said openings, substantially as described.

7. The head with opening a and a cup with a piston and stem, incombination with the base N, having opening d, receiving said stem,whereby the cup may be raised.

8. The head D, with openings 0, in combination with the cups E,withopening in the base, the piston G, with stem F, and the base N, withopenings (1, the said openings d being of less diameter than the cups Eand of greater diameter than the stems F, substantially as and for thepurpose set forth.

9. The head D, with openings 0 and e, in combination with the base N,having openings d f, and the pin Q, substantially as described.

10. The standard A, in combination with head D, having a flanged rim andopenings c, the rotatable sleeve J, carrying a brush adapted to operatewithin the flanged rim of head D and at top of opening 0, substantiallyas and for the purpose set forth. 1
